electronic tatoo

A Bluetooth headset designed to be tattooed onto your throat, the idea is to couple an electronic skin tattoo to a mobile communication device.

Historical perspective: In November 2013, The Week reported "Motorola Mobility has filed a patent application for an electronic tattoo." Google’s
innovative spirit appears to have spread to its Motorola Mobility
subsidiary, which has filed a patent application titled “Coupling an
Electronic Skin Tattoo to a Mobile Communication Device.” Essentially,
it’s a Bluetooth headset “designed to be tattooed onto your throat,”
said Steve Dent in Engadget.com.
Instead of being housed in a phone, the electronic tattoo’s microphone
and transceiver capture vibrations directly from your larynx, freeing up
your hands and theoretically lending your calls greater clarity. It’s
worth noting, however, that Motorola has a reputation for playing “fast
and loose” with the definition of a tattoo, said Chris Velazco in TechCrunch.com.
An earlier “electronic tattoo” from 2011 turned out to be a “thin,
pliable device that adheres to a user’s skin that could be replaced on a
weekly basis.” So perhaps there’s no need to freak out just yet.
